Refactor the code used for arrays to make it re-usable for vectors and arrays.
We already limited extraction at an uppper bound, but when we know the offset we can also start as late as possible. For structs, for example, we now do not expand components that will be irrelevant to the final result.
No need to construct index_exprt when we can just pick the operand out of a vector.
This makes the unit of measurement explicit and thus should help avoid bits/bytes confusion.
This makes the interface much more explicit about what is or isn't supported at moment.
We previously handled unions like PODs.
